"Application Nover'nber 2'1, 1946,-se iammq asv This invention relates to new and useful im- I provements in rakertooth-gages and more particularly ,to a device adapted -for-use in =connection with the sharpening andz-swaging' of saw teeth. V

The primary' feature ofthis invention is to provide a gage of the c'ha'racter referred: to

adapted to'discover irreg-ularitiesfin the cutting edges of saws, saidlgage-being particular-1y adapted for use 'in gagingcircular'sawa Another important feature ol" this invention is to provide a device-ofthis'f{clraracter having an adjustable, resilient bearing-plate adapted to rest on-theedgeso-f the teeth -2515 a saw.

d A further featureof this "invention isto provide a gage of this character that is neat and attractive in appearance, efficient and reliable in operation, relatively inexpensive to manufac ture andotherwise well 'adaptedfor the" purposes for which the same is intended.

' tails of construction and operation as 'more fully J I hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein like numerals refer to like Figure 4 is an enlarged sectional view taken Referring now to the drawing in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of the invention, 3 'the numeral 5 represents an angle iron having a. pair of inwardly inclined threaded openings 6 and Ga at the ends of the horizontal flange 5a 7 v of saidangle iron.

An opening I, is provided in thecenter of horizontal flange 5a, saidjopeningf'l adapted to freely receive the lower threaded end of a-set screw 9 which is provided with a knurled nut Sadat its -upper end bearing against the flange ;'5a.' 7 v The lower end of said screw 9 is threaded ina plate It).

An internally threaded bore H is provided in set screwil, said. bore adapted to receive a gage screw l2 which is adjustable vertically in'screw 9, the lower end I2a of screw [2 extendin ly lightl on the raker tooth, however should the tooth be too high plate Ill will not rest on the cuttin teeth of the blade, and if the raker tooth I3 is too low the lower end l2a of screw 12 will not bear on said raker tooth.

In view of the foregoing description taken in conjunctionwith the accompanying drawings it is believed thata clear understanding of the device will be quite apparent to those skilled in this 7 art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though, there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

' I claim:

1. In a gage for saws, an angle iron having its upper flange horizontal, an opening centrally located in the upper horizontal flange of said angle iron, a vertically adjustable set screw freely thereto andreceiving engaging said set screw, asecond 's'et'screw threaded axially through the "first named set screw and extending downwardly through the resilient plate, said second named. set screw adapted to'bear against the upper. end

boss or the like9b" which is welded orfotherwise v I suitably secured to a longitudinal resilient gage carried in saidopening, a resilient elongated glageplate adjustable vertically by said set screw and having an internally threaded boss fixed of a raker tooth of a saw blade for gaging said raker tooth, and a pair of *setscrews carried by the angle iron and adjacent the end edges of the horizontal flange of said angle iron, said pair of located in the upper horizontal flange of said angle iron, a vertically adjustable set screw slidable in said opening, a resilient gage plate ada j ustable vertically by said set screw and having an internally threaded boss fixed thereto and receivably engaging the set screw, a second set screw threaded axially through the first named set screw and extending downwardly through the resilient plate, said second named set screw engageable with the upper end of a raker tooth ofa saw blade for gaging said raker tooth, and a pair of radially disposed set screws carried by the horizontal flange of the angle iron, the lower ends of said set screws bearing against the re silient gage plate on opposite sides of the first named set screw, to adjust the curvature of the gage plate to conform to the cutting edge of the sa blade.

3. A circular saw gage comprising an angle iron member including a vertical flange and a horizontal flange, a resilient gage plate, manually adjustable means connecting the gage plate to the underside of the horizontal flange for flexing the gage plate to conform to the curvature of the cutting edge of a saw, and an adjustable gage member carried by the horizontal flange and projecting through the plate for gaging one of the teeth of the saw, said means including a set screw, said horizontal flange having an opening therein slidably receiving the set screw, and an internally threaded boss fixed to said gage plate and 'receivably engaging said set screw; said set screw having an internally threaded axial bore receiving said gage member.

4. A circular saw gage comprising an angle iron member including a vertical flange and a horizontal flange, a resilient gage plate, a center adjusting screw connecting the gage plate to the underside of the horizontal flange, said horizontal flange having an opening slidably receiving said adjusting screw, an internally threaded *bo'ss fixed Ito/said gage *plate receivably engaging the adjusting screw, a pair of adjusting screws carried by the horizontal flange adjacent theends thereof and engaging the gage plate adjacent the ends of the latter to adjust the plateto conform, to the curvature of the cutting edge of a"sa'w, and a gauge screw adjustable axially of the center adjusting screw and projecting through the gage plate into gaging position with one of the saw teeth of a saw.
